MongoDB 3.3.11 发布了,MongoDB是一个介于关系数据库和非关系数据库之间的产品,是非关系数据库当中功能最丰富,最像关系数据库的。他支持的数据结构非常松散,是类似 json的bjson格式,因此可以存储比较复杂的数据类型。Mongo最大的特点是他支持的查询语言非常强大,其语法有点类似于面向对象的查询语言,几 乎可以实现类似关系数据库单表查询的绝大部分功能,而且还支持对数据建立索引。

该版本一些新特性:

  • [SERVER-72] - handshake optional parameters for driver name/version

  • [SERVER-3018] - Compression of wire protocol

  • [SERVER-5781] - Allow adding fields to input documents in aggregation's $project stage
